“How does something immoral, when done privately, become moral when it is done collectively? Furthermore, does legality establish morality? Slavery was legal; apartheid is legal; Stalinist, Nazi, and Maoist purges were legal. Clearly, the fact of legality does not justify these crimes. Legality, alone, cannot be the talisman of moral people…But let me offer you my definition of social justice: I keep what I earn and you keep what you earn. Do you disagree? Well then tell me how much of what I earn belongs to you—and why?” — economist Walter Williams in All It Takes Is Guts: A Minority View.
